식용장미인 로즈차와 야생장미 열매인 로즈힙(rosa spp)을 건조시킨 허브차는 오래 전부터 미국과 유럽 등에서 식용되어 왔고 우리나라에도 수입되어 판매된다. 본 연구는 허브차의 기호성에 영향을 미치는 향기 성분을 동시증류추출(SDE)장치를 사용하여 추출하고 gas chromatography와 GC-mass spectrometry를 사용하여 분석 한 결과, 로즈차와 로즈힙차에서 각각 38 종류와 36종류의 향기성분을 동정하였다. 로즈차의 향기성분으로 중요한 화합물은 phenylethyl alcohol, citronellol, menthol, menthone, linalool 및 geraniol 등이었는데 특히 장미향을 띄는 phenylethyl alcohol과 citronellol은 많은 함량 포함되어 있었다. 한편, 로즈힙차에는 menthol, $\alpha$-anethole, $\alpha$-terpinolene, menthone, linalool 및 6-methyl-5-heptene-2-one등이 포함되어 있었는데. 특히 청량감 있는 페프민트 향인 menthol과 달콤한 아니스와 같은 향인 $\alpha$-anethole은 다소 많은 함량 포함되어 있었다.

The purpose of this study was to characterize the aromas of rose tea and rosehip tea. Aroma compounds were extracted by simultaneous distillation and extraction method using a Likens and Nickerson's extraction apparatus. The concentrated aroma extracts were analyzed and identified by GC and GC-MS. Thirty-eight compounds, including phenylethyl alcohol, citronellol, menthol, menthone, linalool and geraniol, were isolated and identified in rose tea. Thirty-six compounds, including menthol, $\alpha$-anethole, $\alpha$-terpinolene, menthone, linalool and 6-methyl-5-heptene-2-one, were isolated and identified in rosehip tea. Large amounts of phenyl ethyl alcohol and citronellol were found in rose tea, while large amounts of menthol and $\alpha$-anethole were found in rosehip tea.

제안 방법
A modified Likens and Nickerson methods, using a simultaneous distillation and extraction apparatus was to extract volatile compound from samples. Fifty grams of each sample was added to 1 1 distilled water containing 5 μ1 of tridecane as an internal standard.
대상 데이터
A gas chromatograph (Shimadzu model 9A) equipped with FID and a HP-5 fused silica capillary column (30 m'0.25 mm i.d/0.25 gm film thickness) was used. The oven temperature was held at 60℃ for 5 minutes and then programmed to 220℃ by 2℃/ min.
0 ml/min. The GC-MS system consisted of a Hewlett-Packard 6890 GC/5973 MS (ionization voltage: 70eV). The GC conditions were the same as those for the corresponding GC analysis, except that helium was used as the carrier gas.
